Recommendation of miniaturized techniques for mechanical testing of fusion materials in an intense neutron source

Abstract Plans for the construction of an intense high energy neutron source for materials development for future fusion reactors call for miniaturized testing techniques which are indispensable for an effective use of the target area. A limited number of techniques is selected and recommendations for their standardization are given. It is the opinion of the authors that international efforts should concentrate on further development of these techniques, especially on a detailed correlation between miniature and bulk behavior.
